Scope

Scope: This standard applies to the design of prevention and control projects for debris flows. This standard specifies the terms and definitions, symbols, basic provisions, engineering design standards, determination of design parameters, design of sub-projects, engineering monitoring design, construction organization design, and construction measures for debris flow prevention and control projects. Where railways, highways, waterways, water conservancy, power, mines, oil and gas pipelines, etc. have special requirements for the design of debris flow prevention and control projects, dedicated studies may be conducted. Main technical content: This specification is compiled based on a comprehensive collection of relevant technical standards for debris flow prevention and control at home and abroad, and a summary of China's experience in the design of debris flow prevention and control projects. It further standardizes the design work of debris flow prevention and control projects and provides sufficient technical support and guarantees for the prevention and control of debris flow disasters. The main content of this specification includes 12 chapters and 14 appendices, mainly covering the scope, normative reference documents, terms and definitions, main symbols, basic provisions, engineering design standards, calculation of design parameters, scheme design, design of sub-projects, engineering monitoring design, construction organization design and construction measures, design changes during construction, etc. In addition, there are 14 appendices, including calculation of debris flow parameters after project treatment, roughness calculation, debris flow impact force, erosion calculation formulas, load analysis and combination of debris flow check dams, calculation method of check dam storage capacity, downstream energy dissipation works, calculation formula of dam foundation seepage deformation, new structures of debris flow check dams, diversion ditches, new struct
